Answer:
7 times
Explanation:
Each meal weighs (24 oz)/(16 oz/lb) = 1.5 lb. The number of meals to be delivered each day is ...
(34.5 lb/day)/(1.5 lb/meal) = 23 meals/day
If we assume that meals can remain in the car from one day to the next, we only need to compute the total number of loads in 4 days.
(23 meal/day)(4 days)/(15 meals/load) = 6 2/15 loads/4-days
That is loading the car 6 times is not enough. They need to load the car 7 times in 4 days.
__
If we assume that meals cannot remain in the car from one day to the next, then the car must be loaded 2 times per day. That's 8 times in 4 days.
The answer depends on your assumptions about loading the car.
